I Application led May 14, 1901. Serial No. 60,149. (No model.)

To all whom, it 71mg/ concern:

Be it known that I, STEPHAN AMAN, a citizen of the United States, and a resident of Port Richmond, in the county of Richmond and State of New York, have invented certain new and-usefulvImprovements in Boilers, of which the following is a specification.

This invention relates to sectional watertube boilers, and has for its object the production of boilers comprising sections which can be easily removed while the boilers are under steam-pressure and a novel construction for conducting the feed-water into 'the boilers and for cleaning both the inside and outside of the diiferent parts.

Figure l represents a fragmentary vertical section of my boiler on the line o; of Fig. 2. Fig.`2 shows fragmentary sections of Fig. 1 on the lines y y and ,c z. Fig. 3 is a fragmentary top view and sections on lines s and t of Fig. l. Fig. 4 shows a vertical cross-section of the steam dome with its connections. Fig. 5 is a partial top view ofv Fig. 4. Fig. 6

is a vertical cross-section through the lower of one of the elbows connected to a manifold over the re-boX, with a vertical section of the valve attached thereto through its vertical axis. Fig. l0 represents one of the tubes over the fire-box with sections through its manifolds on a plane passing through the axis of the tube. Figs. 1l and l2 show end elevations of two sections beyond the fire-box with their manifolds. Fig. 13 represents a partial longitudinal horizontal section of one of the manifolds of the fire-box through its axis. Fig. 14: is an end view of Fig. 13. Fig. 15 showsa plan View of one of the top crossbraces of the boiler.

A Referring to Figs. 1 to 3, the boiler is represented to consist of sections A over the fire-box and sections B and C, the said se'ctions being connected by the mud-drums E and F, and the latter are joined by the pipe G. The sections are covered by cross-braces T, which are partially embedded in fire-clay t3. The manifolds o.' over the re-box are also covered with fire-clay'2f4, :and the manithe manifolds a of the section A by way of the pipes h2, secured in the said manifolds. The pipe G connects the mud-drums E and F, and the conduit g in the pipe G connects with the conduitf in the lower mud-drum F, from which conduits h3 rise to convey the feed-water into the manifolds by way of their internal conduits. It will be noticed that the course of the feed-water is such as always to keep a good circulation in the mud-drums and to keep them clean. A blow-off pipe I with valve i leads from the drum F. A steamdome J is connected with the top manifolds of the sections. A steam-spray pipe K runs vat the sides and back of the boiler, (it only being shown on one-half of the boiler in Fig. 3 to avoid confusion,) with outlet-pipes k, which provide means to clean the outside of the sections.

Doors L and M swing over openings in the lside of the boiler for the purpose of operating sections can be easily removed when theirl joints are broken. A pipe m2 connects the bottom of the steam-dome J with the muddrum F for drawing water from the said dome.

The obj ect of the check-valves O and by-pass with valve P are in case a new section is introduced for repairs and the feed-water is forced therein it might rise up into the steamdome to the check-valve; but by opening the by-pass valve the rising water encounters the IOO steam-pressure and does not rise above. the

common water-level.

Each of the braces T at one end terminatel in U-shaped openings, as t2, to allow the passage of the connections between the manifoldsvand the steam-dome.

The sections B (see Figs. 1, 2, and 11)v coniianges b" of the manifolds b2 and the iiangesv fof the mud-drum F. The Valves R contain ports R R2, the first connecting the main portion of the mud-drum F with the main portion of the manifolds b2 and the port R2 connecting the feed water conduits f' with similar conduits b5 in b2. Openings bw are drilled through each valve, to which are connected secondary valves S, by means of which water can be drained from the sections when the valves R are closed just previous to the removal of the sections for repairs.

Hand-holes are contained in the manifolds b2, which are covered withv the plates b9, secured by means of the crow-feetb11 and bolts 1912. The hand-holes 0.4 at the ends of the manifolds d over the fire-box and the handholes m at the end of the steam-dome J are similar to the hand-holes at the ends of the manifolds b2.

The connections between the manifolds a. over the lire-boxV and the muddrum E (see Figs. 2, 9, 13, and 14) are similar to the .connections between the lower manifolds b2 and the mud-drum F, with the exception that elbows a5 are interposed between the manifolds d and valves R3 leading to the drum E, and

lthe manifolds a contain pipes h2 instead of a v 2. In a boiler, removable sections, comprising manifolds, tubes connecting the manifolds, pipes in the lower manifolds, muddrums under the lower manifolds, Valves interposed between the lower manifolds and l mud-drums, a conduit in each mud-drum, a water-feed pipe connecting with said conduits, risers extending from said conduits,

and leading to the pipes in the lower manifolds. Q

3. VIn a boiler, removable sections, comprising manifolds, tubes Aconnecting the manifolds, an independent conduit contained in each lower manifold, mud-'drums under the lower manifolds, valves interposed between the lower manifolds .and mud-drums, two ports in said valves, one port connected with the conduits in the manifolds and muddrums, and the other ports connecting the main portions ofv the mud-drums' and manifolds.

4. In a boiler, removable sections, comprising manifolds, tubes connecting the said manifolds, independent conduits vin the lower manifolds, mud-drums under the lower manifolds, kvalves interposed between the said lower manifolds and mud-drums, a steamdome connected to the top manifolds, a check'-` valve and by-pass with valve interposed between each top manifold and the steam-dome.

5. A boiler, sections of different lengths in the boiler, the said sections'comprising manifolds, tubes connecting the manifolds, muddrums under thev lower manifolds, doubleported valves connecting the mud-dru ms and lower manifolds, a pipe connecting the muddrum under the shorter' sections, with the mud-drum under the longer sections, a feedpipe entering a conduit under the shorter sections, said conduit extending to and into the mud-drum under the longer sections,

risers extending-from said conduits and lead-` IOO the boiler, the said sections comprising manifolds, tubes connecting the manifolds, muddrums under the lower manifolds, valves connecting the mud-drums and lower manifolds,

a pipe connecting theV mud drums, a feedpipe connecting withv a conduit in the muddrums and in the connectingpipe of said drums, risers extending from said conduits and leading through valves into pipes and conduits in the lower manifolds, a furnace under the shorter sections, a liu'e connection in front of the said shorter sections, a steamdome connected with the top. manifolds, check-valves and a by-pass between each top manifold and the steam-dome, a pipe leading from steam-dome to a lower mud-drum, independent spray-piping with outlets extending around the sections of the boiler.
